ERSC taps Jujutsu creator as CTO

This is a high-signal infrastructure hire: ERSC is betting that AI-driven code volume will expose limits in Git’s remote layer. The thesis is credible, but the company still has to prove that a new storage substrate can scale without disrupting Git-based workflows.

• –von Zweigbergk brings experience across Jujutsu, Git, and Google’s large-scale monorepo tooling.
• –He will continue maintaining Jujutsu as an Apache 2.0 open-source project while ERSC commercializes the server and storage layer.
• –ERSC’s differentiation is infrastructure: high-throughput commits, fast checkouts, large repositories, and collaboration designed for humans and coding agents.
• –Developers should watch whether ERSC supports high-frequency agent commits, stacked diffs, and Git/JJ interoperability without creating platform lock-in.
